In this paper we have studied Bianchi type -I cosmological modelin bimetric theory of relativity and we have considered the matter domain wall coupled with electromagnetic field in x-direction and we observed that, the resulting space -time is free from singularity at cosmic time t = 0.

type plane gravitational waves either for macro field or for micro matter field or for coupled macro and micro matter represented by perfect fluid and scalar meson matter field respectively do not exist in bimetric theory of gravitation formulated by Rosen[1].Only a vacuum model can be constructed.
